Condensation problem on the bedroom wall has led me to lining the wall with a double layer of polystyrene insulation approx now 1/4" thick. This has cured the cond'i problem, but now the tester is do I size the polystyrene with a stronger mix? wallpaper while the size is still moist?or is there another product that will seal the polystyrene layers? I can't afford to do a trial and error as my wallpaper is extremely limited.
No jokes about hot & steamy bedroom antics thanks, I've already done them. :lol:
